HEATER UNIT FOR PIPES.

Applica-tionled July 14, 1922. Serial No. 575,106.

To all wimmt 11m- 1] con cern.:

` Be it known that I, JOHN E. KESTLER, a

citizen of the United States,r4 and a resident of Fountain Inn, in thecounty of Greenville and State of South Carolina, have invented certainnew and useful Improvements in Heater Units for Pipes,*of which the f ollowing is a specification.

This invention relates to a heater unit for pipes.

The object of the invention is to provide a heating unit which may beapplied to pipes taken substantially on the line 2 2 of Fig' 4ure 1.

Figure 3 is a vertical sectional view of the heater unit.

Figure 4 is a similar sectional view taken through the heater and atright angles to the views shown in Figure 3.

Referring to the drawings more particularly, the heater may consist in acasing C, which is preferably cylindrical, and has -its interior linedwith asbestos as at 5L. The lower end of the casing is provided with aclosure 10, while its upper end is open and fitted with a cap K, saidcap having a downwardly extending flange 11 to form a tight closure withthe casing and supporting an electric incandescent lamp 12, the base osaid lam being secured to the cap by the means o boltsv or the like asat 13, and said cap being provided with a suitable opening through whichthere may extend the cord 14 for supplying the -lamp 12 with electriczurreht. The casmgC may be provided with a pair of wings W which areresilient and arcuate in shape. Within these wings there may bepositioned a lining of insulating materbpl such as or the likel asindica wings preferably extending below the casing erally at 15 andwhich may, extend enti y' the length` of the wings W, said C, fas shown,and these extended port-ions being integrally joined as at 9. Theinterior v surfaceof the lining or insulation 15 should be arcuate as at1.6 so that this lining may fit about a pipe P.

'At a point in horizontal alignment with the lamp 12 there should beprovided an Vopening17 whichshould extend through the insulation L ofthe casing C, the casing Cv itself, and the lining or insulation 15.

As is shown the wings W substantially encircle the pipe P to be heatedand these wings theretore substantially form a casing' 'wlth insulatingmaterial therein adapted to surround the pipe to which the lamp 12 isadapted to supply heat through the opening 17.

For further protecting the pipe P, there is provided an extensiongenerally indicated by the reference character E and which consists in apipe section recessed longitudinally `and made of resilient material.Suitable insulation 18 is provided for this sectionpof the pipe. Thelower end ortion of the extension is not lined with-insu ation and isadapted to telescope about the wings W. i

It .is thought from the description heretofore given that the operationof this `present device may be entlrely and clearly understood.- Thedevice is particularly useful in the winter for preventing freezin waterpipes in the house or buildings w ich are exposed to extremely lowtemperatures.

The device may be applied to a pipe in a short interval of time and witha small amount of labor, and the cord 14 may be led to a suitable sourceof electric current Sup-r ply for energizin the lamp 12. The removablefeature o theldevice is valuable in that it permits the same to be soldat any store and sold in sizes so that they may be utilized inconnection with any diameter of Pipe I claim: f i i 1. In combination, apipe, insulation about said pipe, said pipe having an exposed portionwith respect to said insulation, an enclosure arranged in close relationto the insulation about the pipe, and said enclosure havin anopening' 1nregister with the expose portions of said-pipe,

and means whereby a heating medium mayV -be provided `in said enclosure.

`2. In combination, rounding said p ipe,

a pi a casing sur-- iusuilzion interposed between said casing and pipe,said casing and insulation having aligned openings to expose a portionof said pipe, and a heating chamber communicating with said openings.

3. In combination, a pipe, a casing surrounding said pipe, insulationinterposed between said easing and pipe, said casing and insulationhaving aligned openings to expose a portion of said pipe, a secondcasing having an opening comi-nunicating with said openings, and meansfor positioning a heating element in the last named casing.

4. In combination,l a pipe, a casing surrounding said pipe, insulationinterposed between said casing and pipe, said casing and insulationhaving aligned openings to expose a portion of said pipe, a secondcasing having an opening communicating with said openings, and means forsuspending an electric lamp in the last named casing.

5. In combination, a pipe, a casing sui;- rounding said pipe, insulationinterposed between said casing and pipe, said insulation and casinghaving aligned openings to expose a portion-of the pipe, a second casingcarried by the rst named casing and having an openingeommunicating withthe opening of the first named casing, and a heating chamber positionedin the second casing. n

6. In combination, a pipe, a casing surrounding said pipe, insulationinterposed between Said casing and pipe, said insulation and casinghaving-aligned openings to expose a portion of the pipe, a second casingcarried by the first named casing andhaving an opening communicatingwith the opening of the first named casing, a heating chamber positionedin the second casing, and an extension from'the irst named casingencircling other portions of the pipe.

7. Inl combination, a pipe, a casing surrounding said pipe, insulationinterposed between said casing and pipe, said insulation and casinghaving aligned openings to expose a portion of the pipe, a second casingcarried by the first named casing and having an opening communicatingwith the opening of the first named casing, a heating chamber positionedin the second casing, an extension from the rst named casing encirclingother portions of the pipe, and insulation material interposed betweenthe casing section and the pipe.
